GUS/ MAN United States Patent MULTIPLE COIVIPARTMENT RECEPTACLE Carl H. Buecker and John R. Cushman, Fort Wayne, Ind., assignors, by mesne assignments, to Eastman Kodak Company, Rochester, N. Y., a. corporation of New Jersey Application December 4, 1956, Serial N0. 626,171 6 Claims. 01. 220-22 The invention relates to a multiple compartment receptacle and more particularly to such a receptacle which permits thin, discrete elements to be inserted and withdrawn from either end of the receptacle and from any of one of a plurality of compartments and which permits transporting of the elements arranged in the compartments in stacked relation as a unit.

Open end receptacles which permit insertion of a stack of thin elements in one end and withdrawal of the lowermost element by a reciprocating member from the other end are well-known in the feeding and sorting arts. However, these receptacles are usually formed from or are a part of the apparatus and are not removable from the apparatus. In instances where a number of such receptacles are arranged side by side, the elements are usually withdrawn from the receptacle and then transported by a conveying mechanism to another station so.

that there is no need for insertion and withdrawal of the elements from both ends of the receptacle.

The present invention contemplates a multiple compartment receptacle in which both ends of the compartments are open, in which thin, discrete elements can be retained in stacked relation in each compartment, in which the elements can be inserted and withdrawn from either end, in which the receptacle serves as a part of the apparatus when used therewith, and in which the receptacle can be used as a storage device for the elements when not associated with the apparatus. Such a receptacle is utilized in apparatus for sorting, selecting and for collating information bearing elements, such as small pieces of photographic film or photographic paper. Since these elements are of the order of five-eights of an inch by an inch and a quarter in size, it can be readily appreciated that they are not readily adapted to be manipulated or transported by hand. As a result, a multiple compartment receptacle serves to provide both a part of the apparatus as well as a transport and storage means for these elements. Since the receptacle must form a part of the apparatus for manipulating the elements, it must be accurately and rigidly formed. The receptacle must also be sufiiciently light in weight in order to permit an operator to place a fully loaded receptacle in position on the apparatus and to carry a fully loaded receptacle from the apparatus to the storage place therefor.

The receptacle devised for the purposes described above comprises a plurality of plates, many of which are identical in size and shape, which can be easily assembled to provide a light weight multiple compartment receptacle. One group of plates are provided with spaced tabs along opposed edges thereof and with pairs of spaced apertures arranged longitudinally and transversely of the plates. Each pair of these plates is maintained in spaced, parallel relation by partition members, each of these partition members also being provided with tabs which are inserted in the apertures in the plates. End plates, which are also provided with pairs of spaced apertures arranged longitudinally and transversely thereof, receive the tabs on the plates to retain the plates in proper position. By varying the width of the end plates, the number of compartments in one direction. can be changed and by'varying the width of the plates, the number of compartments in the other direction can also be changed. It is to be understood, of course, that the height and, hence, the number of elements to be contained in the stacks can also be changed. One end of the assembled plates is covered by an end plate provided with openings arranged both longitudinally and transversely thereof and in alignment with each of the compartments. Each opening, however, is provided along one set of opposed edges with lips for retaining the elements in their respective compartments. These lips are of such size so as to permit the lowermost element to be bowed past the lips when it is inserted or withdrawn from a compartment. From the more com plete description which follows, it will be evident the structure of the receptacle lends itself readily to fabrication, to variation in size, and to fulfilling a requirement not heretofore attainable by known receptacles.

The primary object of the invention is, therefore, to provide a multiple compartment receptacle which permits insertion and withdrawal of thin, discrete elements from either end and any oneof the compartments.

Another object of the invention is to provide a multiple compartment receptacle which permits thin, discrete elements to be stacked therein and which can, be utilized to transport and store said elements.

Still another object of the invention is to provide a multiple compartment receptacle which can. be readily fabricated and in which the number of compartments can be readily varied.

And yet another object of the invention is to provide an arrangement of plates which are readily and easily assembled whereby an open end multiple compartment receptacle is formed which is. rigid, sturdy and light in weight.

Other objects and advantages will be apparent to those skilled in the art by the description which follows.

Reference is now made to the accompanying drawings wherein like reference numerals designate like parts and wherein:

Fig. 12 is a detail plan view of a photographic element, such as may be used in conjunction with the device shown.

While the invention is disclosed as a multiple compartment receptacle for thin, discrete elements, such as photographic film and paper, it is to be understood and will be readily apparent to those skilled in the art that the receptacle described hereinafter can be easily adapted to uses for other elements whether paper, metal, plastic or similar materials. In addition, the structure of the receptacle lends itself to fabrication for many other uses than that disclosed. Accordingly, the structure set forth herein is merely illustrative of the invention and may be easily altered to obtain a similar receptacle for elements of a different size or shape or having a different number of compartments.

With reference to Fig. 12, the element 20 is a small piece of photographic film which is rectangular in shape and which is provided with an elongated slot 21 adjacent one end for handling a plurality of said elements on a stick as a unit. Element 20 comprises an image area 22 and/ or a code area 23, image area 22 comprising one to twelve images and code area 23 comprising an area equivalent to two images transversely of element 20, as shown in Fig. 12, or any number of such areas. Accordingly, element 20 may comprise images and code in different arrangements or may comprise only code.

Since elements 20 contain code which is representative of information with respect to one or more of the images on the element, such elements can be sorted, collated and filed in accordance with such code. To eliminate handling of large numbers of such elements, the multiple compartment receptacle, designated by the numeral 25 in Figs. 1, 2, 9 and has been devised. Receptacle 25 can be utilized as a file for stacks of elements 20 and can also be utilized as a unit of the sorter and collator into which the elements are inserted or withdrawn from the bottom of the receptacle. The number of compartments in receptacle 25 can vary depending on the size of element'20, the type of apparatus with which it is to be used, the weight of the unit when fully loaded, etc. The receptacle shown in Figs. 1 and 2 comprises fifty compartments and the height of the receptacle is such that each compartment will retain a stack of 2000 elements or a total of 100,000 elements when fullyloaded. The Weight of receptacle 25, when fully loaded, is approximately twenty-five pounds so that an operator can easily position or remove the loaded receptacle with respect to the file or apparatus.

, As shown in Figs. 1 and 2, receptacle 25 comprises a plurality of plates 26, a plurality of partition members 27, two side plates 28 and an end plate 29. To each of side plates 28 a handle 30 is secured, as by rivets or welding, the handle being in the form of a rectangular frame having an L-shaped cross section with a grip 31 fixed to the top thereof. On the lower side of the lefthand handle, as seen in Fig. l, a block 32 is secured to the inner side. A similar block 33 is secured to the underside and is provided with a counter-sunk hole 34. The handle at the right side has similar blocks 35 and 36 fixed thereto, the block 36 having studs 37 extending therefrom. Hole 34 and studs 37 are utilized to position the receptacle with respect to the apparatus and in a file cabinet by means of a stud which engages hole 34 and spaced holes for receiving studs 37. It is believed that a better understanding of the invention will be obtained if the various plates, etc., comprising receptacle 25 are first described per se with the procedure for assembling the receptacle then following.

With reference to Figs. 4 and 5, plate 26 is provided along the opposed edges 40 and 41 with spaced tabs 42. Along the lower edge 43, a plurality of spaced locating tabs 42' are arranged for a purpose to be described hereinafter. A narrow portion 44 of plate 26 along edge 45 10. Partition members 27 are then arranged betweenis formed at an angle to plate 26, as shown in Fig. 4,. and is flared at the extremities thereof, as designated by numeral 46. Both longitudinally and transversely of plate 26, a plurality of pairs of apertures ,47 are arranged. These apertures, it will be noted from Fig. 5, are aligned both longitudinally and transversely with tabs 42; however, the spacing between facing apertures of each pair of apertures in a transverse direction is determined by the desired width of the compartment. The separation between the apertures in each pair is equivalent to the desired spacing between compartments, as described more fullyhereinafter. Adjacent edge 45 and between the first two sets of apertures 47, plate 26 is provided with a plurality of square openings 48 which are aligned with apertures 47. Also, adjacent edge 43 and between the two lowermost sets of apertures 47, plate 26 is provided with a plurality of square openings 49. Between each pair of apertures 47 and aligned therewith, plate 26 has stamped therefrom a plurality of tongues 50 which are formed at right angles to plate 26 in the same direction, as shown in Fig. 4, and which provide a plurality of rectangular apertures 51.

Side plate 28, as shown in Figs. 6 and 7, is formed over at edges 55 and 56 to provide extensions 57 which are normal to plate 28. Along lower edge 58, spaced locating tabs 59 are formed and a narrow portion 60 adjacent upper edge 61 is formed at an angle to plate 28 with the flared ends 62, as shown in Fig. 7. Along each of edges 55 and 56 a plurality of apertures 63 are arranged in spaced relation and in accordance with the spacing of tabs 42 on plate 26. Pairs of spaced apertures 64 are arranged both transversely and longitudinally of plate 28 and in alignment with apertures 63.

As with respect to plate 26, the space between apertures 64 in each pair is equivalent to the spacing between adjacent compartments whereas the spacing between facing apertures of each pair of apertures 64 in a transverse direction is determined by the desired length of the compartment. Adjacent edges 61 and 58, plate 28 is provided with square openings 65 and 66 which are arranged transversely of plate 28. It will be noted, however, that openings 65 and 66 are farther removed from their respective edges than openings 48 and 49 for a reason to be described hereinafter.

Partition member 27, as shown in Fig. 8, is provided along its edges 68 and 69 with spaced tabs 70, said tabs being spaced in accordance with apertures 47 in plate 26. Also, along edge 71 there is provided two locating tabs 72. The narrow portion 73 along edge 74 is formed at an angle to plate 27 and the edges 75 of said portion are flared, as shown.

End plate 29, as shown in Fig. 2, is formed with bottom 77 and a continuous flange 78. The bottom 77 is provided with a plurality of apertures 79 arranged longitudinally and transversely thereof. These apertures are arranged in accordance with the arrangement of the compartments. As shown in Fig. 3, each of apertures 79 is provided with two notches 80 in opposite sides. The arrangement of apertures 79 and notches 80 is such that locating tabs 59 and 72 on side plates 28 and partition members 27, respectively, will extend into notches 80 and locating tabs 42' on plates 26 will extend into the ends of each aperture. As will be evident from the description which follows, tabs 59 will engage only the outer notches 80 in the two outer rows of apertures in end plate 29 because only two side plates are used. Since notches 80 are deeper than the thickness of tabs 59 and 72, a lip 81 is provided along the opposed sides of apertures 79. These lips 81 serve to support the stack of elements 20 in each compartment and engage only the marginal edges thereof, as shown in Fig. 3.

Receptacle 25 is formed by first arranging a pair of plates 26 in parallel, spaced relation with tongues 50 facing or projecting toward each other as shown in Figs. 9 and plates 26 and at right angles thereto with tabs 70 extending through apertures 47. As seen in Fig. 9, partition members 27 are thus arranged in pairs and in spaced, parallel relation, nine such pairs of members 27 being utilized toproduce ten compartments, and from Fig. 1 it will be noted that plate 26 is provided with nine transverse pairs of apertures 47. Upon insertion of tabs 70 into apertures 47, the tabs are formed over as shown in Fig. 9 and partition members 27 are securely fixed in position and in relation to plates 26. To insure the size of the compartment formed by plates 26 and partition members 27, solid gauge of the allowable dimensions of the compart ment can be placed within the compartment before tabs 70 are formed over. Then, upon forming over the tabs, the size of the compartment is maintained within the re quired tolerances and, at the same time, plate 26 and partition members 27 will be arranged to provide true and square corners throughout the length of the compartment.

Upon completion of the forming of five such sets of plates 26 and partition members 27, this group is arranged so that the pairs of plates 26 are in spaced, parallel relation with the open ends and tabs 42 aligned so as to receive side plates 28. As shown in Figs. 9 and 10, tabs 42 on plates 26 are inserted in aperture 63 and the pairs of spaced apertures 64 with extensions 57 overlying outer plates 26, plates 28 being provided with four such pairs of apertures 64 for receiving the four inner pairs of tabs 42 and the outer tabs 42 being inserted in apertures 63.

When tabs 42 are formed over, a fifty compartment unit is thus formed. At this stage narrow portions 44, 6t), and 73 together with flared ends 46, 62, and 75 combine to form an opening at one end which is larger than that at the other end, see Fig. 10. In this assembled relation, tongues 59 between each pair of partition members 27 serve to make the structure more rigid throughout its height. However, to make the receptacle 25 more rigid at its extremities, channels 83 and 84 are inserted in the aligned openings 48 in plates 26 and in the aligned openings 65 in side plates 28, respectively. As shown in Fig. 11, channels 33 and 84 are substantially U-shape in cross section and at each end are provided with slots 85 to form tabs 86 which in assembled relation can be formed over on the outer plates 26, as shown in Fig. 10. Since channels 83 are arranged between partition members 27 and channels 84- are arranged between plates 26, the number of channels used will differ as well as the lengths. Because o-f this arrangement, it is also necessary to arrange one group of channels above the other, as shown in Fig. 10, which accounts for the difference in location of openings 48 and 65 as described above.

End plates 29 is then placed over the other end with flange 73 arranged over extensions 57, as shown in Fig. 1. As described above, locating tabs 42 are positioned in the ends of apertures 79 and locating tabs 59 and 72 are positioned in notches 8t Strips 88 which are provided with spaced tapped holes are positioned in aligned openings 49, and strips 89 which are also provided with spaced tapped holes are positioned in aligned openings 66. End plate 29 is retained in position by screws 90 and 91 which pull strips 88 and 89 against the lower edges of openings 49 and 66 and end plate 29 against the lower edges 43, 58 and 71 of plates 26, side plates 28, and partition members 27. Strips 88 and 89 are sutficiently long so that the extreme ends are supported by the lower edges of the openings in the outermost plates.

From the above description, it is evident that the disclosed structure comprises a very minimum number of different parts to provide a multiple compartment receptacle. In addition, the structure set forth is extremely rigid, light in weight and readily adapted to contain a very large number of the elements described. While the structure has been described with respect to a 5 x compartment receptacle, the number of compartments can be easily increased or decreased without departing from the spirit of the invention. Since many modifications of the structure disclosed will be apparent to those skilled in the arts, the invention is not to be limited to the embodimerit described and illustrated, but is defined by the appended claims.
